Frequently Asked Questions (FAQs)
1. What is Testosterone, and Why is it Important for Men?
Testosterone is the primary male sex hormone produced in the testes. It is responsible for many critical functions in the male body, including:
Libido regulation (sex drive)
Muscle mass and strength maintenance
Sperm production and fertility
Bone density and cardiovascular health
Mood regulation and cognitive function
As Dr. Vijayant Govinda Gupta explains, “Testosterone is not just about muscles and libidoโit’s about the essence of manhood. It affects how you feel, how your body functions, and even how your mind operates. Low testosterone doesn’t just impact your body physically; it also takes a toll on your mental and emotional health.”
The hormone is vital for maintaining energy, mood stability, and sexual function. When testosterone levels decline, men can experience an array of issues that affect their overall quality of life, such as chronic fatigue, reduced libido, erectile dysfunction, and cognitive difficulties. This decline often begins after the age of 30, when testosterone levels start to fall gradually each year.

2. When Should a Man Get His Testosterone Levels Checked?
Knowing when to get your testosterone levels checked is crucial, especially as you age. Testosterone levels naturally fluctuate throughout the day and decrease over time. But for some men, these levels decline more rapidly, leading to noticeable symptoms that may disrupt daily life.
Key Symptoms of Low Testosterone (Low T)
According to Dr. Gupta, men should consider getting their testosterone levels tested if they experience any of the following symptoms:
Fatigue: Persistent tiredness or lack of energy, even after a full night of rest.
Decreased sex drive: Noticeable decline in sexual interest and libido.
Erectile dysfunction: Difficulty achieving or maintaining an erection.
Muscle weakness: Unexplained loss of muscle mass or difficulty gaining strength.
Mood disturbances: Feeling irritable, depressed, or unmotivated.
Increased body fat: Particularly around the midsection, without major changes in diet or exercise.
Dr. Gupta advises that men over 35 should establish a baseline testosterone level by getting tested even if they feel healthy. “A baseline test is important because testosterone plays a role in so many aspects of your health. By tracking your levels over time, we can intervene early if thereโs a noticeable decline, potentially preventing serious conditions like heart disease and metabolic issues.”

3. How is Testosterone Testing Done?
Testosterone testing is typically a simple blood test that measures the amount of testosterone in your bloodstream. While itโs recommended to take the test in the morningโwhen testosterone levels are at their peakโit can be taken at any time of day depending on the symptoms you’re experiencing. Dr. Gupta highlights that the timing of the test is important but not always definitive:
“The common belief is that testosterone must always be tested in the morning for accurate results. While it’s true that testosterone peaks in the morning, it’s more important to understand how your body behaves throughout the day. If your symptoms occur later in the day, we may need to check levels at multiple times.”
Types of Testosterone Tests
Total Testosterone: This measures the total amount of testosterone in your blood, including testosterone that is bound to proteins like sex hormone-binding globulin (SHBG) and albumin, as well as free testosterone.
Free Testosterone: This measures the portion of testosterone that is not bound to proteins and is available to tissues for use. Some doctors consider free testosterone to be a more accurate measure of testosterone activity in the body.
What Happens During the Test?
1. The test is usually performed in the morning, between 7 AM and 10 AM, to capture testosterone levels when they are highest.
2. A healthcare provider will draw a small blood sample from a vein, usually from your arm.
3. The blood sample is sent to a laboratory for analysis, and results are typically available within a few days.
Dr. Gupta emphasizes that if the results show low testosterone levels, itโs important to recheck multiple times. “Since testosterone levels fluctuate throughout the day, one low result may not tell the whole story. A follow-up test is often needed to confirm any diagnosis.”

4. How Does Lifestyle Affect Testosterone Levels?
Your lifestyle plays a significant role in maintaining healthy testosterone levels. Certain habits and lifestyle factors can either boost or suppress testosterone production.
Diet: Eating a poor diet high in processed foods and sugar can lead to weight gain and lower testosterone levels. On the flip side, a balanced diet rich in healthy fats, proteins, and micronutrients (like zinc and magnesium) is essential for testosterone production.
Exercise: Regular physical activity, especially weightlifting and resistance training, can significantly boost testosterone levels. However, excessive exercise or overtraining can have the opposite effect, leading to lower levels due to stress and recovery demands.
Sleep: Sleep is crucial for maintaining optimal testosterone levels. Studies show that men who sleep less than 5 hours a night have significantly lower testosterone levels than those who get 7โ9 hours of sleep.
Stress: Chronic stress causes the body to release cortisol, a hormone that suppresses testosterone production. Managing stress through practices such as meditation, yoga, or regular exercise can help maintain healthy testosterone levels.
Dr. Gupta states, “Testosterone is extremely sensitive to your lifestyle. If you’re constantly stressed, not sleeping well, or eating poorly, your testosterone will suffer. Even simple changes like improving your diet and getting enough sleep can make a significant difference.”

5. Are Some Men More Sensitive to Testosterone?
Yes, individual genetics and androgen receptor sensitivity play a significant role in how testosterone affects the body. Androgen receptors are proteins in tissues such as muscles, bones, and the brain, which testosterone binds to in order to exert its effects.
Dr. Gupta explains: “Some men have highly sensitive androgen receptors, meaning they may experience the effects of testosterone even at lower levels. On the other hand, men with less sensitive receptors might need higher levels of testosterone to feel the same effects. This is why two men with identical testosterone levels can have very different experiences.”
Factors That Influence Testosterone Sensitivity:
Genetic variability: Some men are genetically predisposed to have more active androgen receptors, meaning their bodies respond more effectively to testosterone.
Body composition: Men with lower body fat percentages and more muscle mass often experience a stronger response to testosterone.
Age: As men age, androgen receptor activity may decrease, making the body less responsive to normal levels of testosterone.
Because of this variability, a “normal” testosterone level might not be sufficient for all men. Dr. Gupta emphasizes that testosterone replacement therapy (TRT) should be personalized. “It’s not enough to just look at the numbers. We need to consider how the patient feels, their lifestyle, and other hormones in their system to create a tailored treatment plan.”

6. Which Other Hormones Influence Testosterone in the Body?
Testosterone doesnโt act in isolation. It interacts with several other hormones in the body, which can influence its production, function, and overall impact. Dr. Gupta stresses that balancing other hormones is just as important as maintaining healthy testosterone levels.
Estrogen: Men produce small amounts of estrogen, and the balance between testosterone and estrogen is crucial. If too much testosterone is converted into estrogen, men can experience side effects such as breast enlargement (gynecomastia) and mood swings.
Cortisol: Chronic stress raises cortisol levels, which can suppress testosterone production. Managing stress is essential for keeping cortisol under control and maintaining healthy testosterone levels.
Thyroid hormones: Thyroid dysfunction, particularly hypothyroidism, can lead to lower testosterone levels. Since the thyroid regulates metabolism, any imbalance can affect how testosterone is produced and used.
Insulin: Insulin resistance, often seen in obesity and type 2 diabetes, can reduce testosterone levels and lead to increased body fat and reduced energy.
Dr. Gupta adds: “Itโs not just about your testosterone level; itโs about the balance between all your hormones. Men with high cortisol or insulin resistance may experience the symptoms of low testosterone, even if their levels are technically normal.”

7. What Are the Symptoms of Low Testosterone?
Low testosterone, or Low T, can manifest in various ways, including both physical and psychological symptoms. These symptoms can affect daily functioning, mood, and quality of life.
Physical Symptoms:
Persistent fatigue
Decreased muscle mass and increased body fat
Shrinking testicles
Low libido and erectile dysfunction
Physical Symptoms (continued):
Hair thinning or loss
Reduced bone density, leading to fractures
Infertility or reduced sperm production
Mental and Emotional Symptoms:
Mood swings or increased irritability
Feelings of depression or anxiety
Decreased motivation or drive
Difficulty concentrating or experiencing “brain fog”
Low self-esteem or confidence
According to Dr. Gupta, the mental and emotional symptoms are often overlooked but are just as critical as the physical ones. He explains: “Testosterone isn’t just a ‘sex hormone.’ It plays a vital role in how men feel and function on a day-to-day basis. Low testosterone can lead to feelings of depression, lack of motivation, and a general sense of malaise thatโs often mistaken for other issues like stress or aging.”
Dr. Gupta also points out that men with low testosterone may not exhibit all symptoms, and some may experience only a few of these issues. However, if you are experiencing a combination of these symptoms, itโs worth discussing testosterone testing with your doctor.

8. How Accurate Are Testosterone Screening Tests?
Testosterone screening tests are generally accurate when performed correctly. However, as Dr. Gupta explains, various factors can affect the accuracy of the test, and itโs important to consider these factors to get a complete picture of your testosterone levels.
Factors That Can Affect Testosterone Test Accuracy:
Time of day: Testosterone levels peak in the morning and drop throughout the day. For this reason, most doctors recommend testing between 7 AM and 10 AM. However, if your symptoms occur later in the day, Dr. Gupta may recommend testing at different times to capture more comprehensive data.
Stress levels: Elevated cortisol from stress can temporarily lower testosterone levels. If youโre under high stress at the time of testing, the results may not accurately reflect your typical testosterone levels.
Sleep: Lack of sleep can lower testosterone, so it’s important to ensure that youโre well-rested before getting tested.
Illness or surgery: Recent illness or surgery can temporarily decrease testosterone levels, so itโs best to wait until youโve fully recovered before testing.
Medications: Certain medications, such as corticosteroids and opioid painkillers, can interfere with testosterone production.
Dr. Gupta emphasizes that testosterone levels fluctuate naturally, so itโs not uncommon to have varying results from one test to another. “One low result doesnโt always mean you have low testosterone. If your test results show low levels, we often recommend retesting at different times of day or over several weeks to get a clearer picture.”
He also mentions that doctors often use multiple tests to confirm a diagnosis of low testosterone. “We may perform the initial screening, but if your levels come back low or borderline, follow-up tests will be conducted to ensure accuracy before proceeding with any treatment.”

9. Should I Consider Testosterone Replacement Therapy (TRT)?
If your testosterone levels are consistently low, and youโre experiencing significant symptoms, Testosterone Replacement Therapy (TRT) might be an option worth considering. TRT helps restore testosterone levels to a healthy range, potentially improving symptoms such as low energy, decreased libido, and mood disturbances.
Dr. Gupta explains the benefits and potential risks of TRT: “TRT can be life-changing for men with low testosterone, but itโs not a ‘quick fix.’ You need to understand both the benefits and the potential side effects before starting treatment. Itโs important to work closely with your doctor to monitor your progress and ensure that TRT is the right choice for you.”
Benefits of TRT:
Increased energy and vitality
Improved sexual function and libido
Enhanced muscle mass and strength
Better mood and cognitive function
Improved bone density and cardiovascular health
Potential Risks of TRT:
Increased red blood cell count, which can raise the risk of blood clots
Enlargement of the prostate or worsening of prostate issues
Acne or oily skin
Sleep apnea or worsening of existing sleep apnea
Fluid retention and weight gain
Dr. Gupta advises men considering TRT to undergo thorough testing and consult with a healthcare provider experienced in hormone management. “TRT is not a one-size-fits-all solution. It’s about finding the right dose, the right treatment method, and closely monitoring the patient over time to ensure the best outcomes.”
